SCHOOL DESK AND SEAT.

Specification of Letters Patent.

Patented Feb. is, 1918.

Application filed May 13, 1916. Serial No. 97,231.

To all whom it may concern:

Be it known that I, EDWARD M. MGNA- MARA, a citizen of the United States of America, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in School Desks and Seats, of which the following is a specification.

This invention relates to combined desks and seats for school room and like uses, and has for its objects:

To provide a simple and durable structural formation and association of parts of a combined school desk and seat, by means of which a turning adjustment of the same in a horizontal plane can be effected in an effective and expeditious manner, to afford the proper light effect and permit the pupil to face any part of the school room.

To provide means whereby the deskvand associated seat are foldingly connected together, so that'the seat and accessories can be folded up from the floor and onto the desk to permit of the convenient sweeping and scrubbing of the school room floor. Said seat in the folded position being adapted to close the desk entrance and cover over the top of the desk and prevent any papers thereon being blown away or otherwise disturbed during the operations of cleaning and the direct ventilation of the school room.

To provide a structure in which the seat is interchangeable with the desk upon the supporting pedestal of said desk, and so that said desk may be removed and replaced by the seat when it is desired to temporarily convert the school room into an assembly hall. All as will hereinafter more fully appear.

In the accompanying drawings:-

Fig. 7, is a side elevation with parts in section, illustrating a modified form of one portion of the present invention.

Similar reference numerals indicate like parts in the several views.

The present combined school desk and seat structure is substantially the same as that shown in my prior Letters Patent, No. 1,194,527, dated August 15, 1916, and is in part a division of the subject matter originally claimed in said prior application. And the present improvement comprises a detail construction of parts as follows:

1 designates the desk body of any conventional form, and preferably provided with avertical airduct 2, at its forward end, for warming and Ventilating purposes as in my before mentioned application. The supporting pedestal for the desk body is preferably of a hollow construction and communicates'at its'lower end with a ventilating or warm air duct or passage 4: below the school room floor, and at its upper end said pedestal is in communication with air duct 2 of the desk body 1 aforesaid.

The desk supporting pedestal aforesaid, comprises a lower or main section 5, adapted for fixed attachment to the school room floor, and an upper section 6 slidable vertically on said main section 5 and carrying on its upper end the desk body 1 aforesaid. The sections 5 and 6 in the present structure have a cylindrical shell form adapting them for the above mentioned vertical adjustment, as well as for the turning adjustment in a horizontal plane, of the upper section 6 and the desk body 1, carried thereon, as hereinafter described in detail.

7 designates a series of orifices formed in the wall of the lower section 5, near the lower end of the same, to provide communication between the interior of the school roomand the interior of said pedestal section.

8 designates an apertured register collar associated with the fixed section 5 and its ori fices 7 aforesaid, and adapted by a turning adjustment to regulate the extent of communication between the interior of the school room and the interior of the desk pedestal.

9 designates a vertically spaced series of quired vertical adjustment and at the same time secured against any independent turning movement between the parts. By placing the said pin 10 in any of the opposed 4 sets of holes 9 in the upper section 6, with slot and bolt the shank ofthe pin resting on the top margin of the lower section 5, as illustrated 1n Fig. 1, the two sections are secured at the desired vertical adjustment, and at the same time the upper section 6 is capable of receiving an independent adjustment in a horizontal plane for the purpose hereinafter set forth in detail. I

11 designates a bracket sleeve clamped upon the upper pedestal section 6 near its lower end, and provided with a pair of cars for the passage of the transverse bolt 12, by which said sleeve is clamped in place, and by which the hereinafter described connecting yoke of the seat is pivotally connected to thedesk pedestal.

13 designates the connecting yoke or frame above referred t0,1anCl which is preferably of the U shape shown in Fig. 1. One vertical arm 1 1 of said yoke is provided with pivot ears at its upper end for pivotal engagement with the bolt 12 above described. The companion vertical arm 15 of said yoke is of cylindrical shell form, and in the pres ent improvement constitutes the lower member or section of the supporting pedestal of the seat 16, which is associated with the desk body 1 aforesaid and to such end said arm 15 preferably provided with a reinforcmg inner tube section 17 at its lower end which is .adapted to rest upon the school two parts slidingly associated together in order that the seat 16 aforesaid, may be adjusted toward or away from the desk body to suit the bodily convenience of the pupil as well as permit an assembly adjustment of the parts so that the seat back will fit and cover the desk top when said seat back is swung up away from the floor for such purpose. In the construction shown in Fig. 1,.said parts slide one within the other and the extent of the adjustment is limited by an elongated formation 18, as shown in Fig.1. Y r

19 designates the upper section of the seat 7 holes formed in the Walls of the lower and upper seat pedestal sections 15, 19, and

adapted to receive" a cross-pin or bolt 21, to

secure the parts together at any desired vertical adjustment. Y

The seat 16 is of any conventional form, preferably provided with a hinged back 16 and is fixedly secured to the upper end of the upper, pedestal section 19, as illustrated in Figs. 1 and 2. V

In the construction shown in Figs. 1 to 6,

inclusive, the normal position of the combined desk and seat parts is shown in full lines in Fig. 1, And in the described con struction, the seat 16, and carrying yoke 13;, are adapted to be moved up into the position shown in dotted lines in said Fig. 1, clear of the school. room floor, and with :the seat 16 closing theentrance of the desk body 1 and the seat back 16 resting upon the top of said desk body. lVith the parts in tlris last described position, articles on or in the desk body 1 are fully protected, and the cleaning of the school room floor is not impeded by the seat and its connections.

designates a series of apertures formed in'the wall of the upper section '19 of the seat pedestal, to admitthe passage of air when the seat 16 is transposed in the manner hereinafter described,- and constituting a part of the heating and ventilating systemof the school room. i

A material part of the present invention consists in making the upper section. 19 of the seat pedestal, and the upper section 6 of the desk pedestal of counterpart formations, in order that the desk-body 1 with its tached upper pedestal section 6 may be entirely removed and stored away, and their place taken by the seat 16 and itsattached pedestal section 19, whenit is desired to temporarily convert the school roominto an assembly hall. In such transformation, the intermediate connecting yoke .13 will also be detached and stored away. 7

In the modified construction shown in Fig. 7, the desk body 1 and seat 16 are associated together upon and wholly carried by hollow cylindrical section 6 of the same detail structure as that described in connection with the desk supporting pedestal shown in Fig. l, and the said upper pedestal section 6 will be supported by a lower pedestal section 5 of the same construction as that heretofore described in the preferred form of the present invention. 7 In the present invention the adjustment of the combined-desk body and seat in a horizontal plane, is materialfeatureof novelty, in that with such provision the parts can be effectively and expediently turned'so that the natural lighting of the school room will come in the proper direction past the desk body to reduce the visual strain upon the pupil during school attendance and study.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is

1. In a combined school desk and seat, the combination of a desk supporting pedestal comprising upper and lower sections connected together for turning adjustment in a horizontal plane, a desk body mounted on the horizontally adjustable section of said pedestal, and a seat connected to and turning with said horizontally adjustable pedestal section, substantially as set forth.-

2. In a combined school desk and seat, the combination of a desk body, a pedestal sup porting the same and comprising a pair of cylindrical shells or sections connected together for a turning adjustment in a horizontal plane, a seat provided with a cylindrical section on its underside, and a connecting frame connected to the upper section of the desk pedestal. and provided with a vertical portion adapted to fit the cylindrical section of the seat, the said vertical portion of the connecting frame and the lower section of the desk pedestal having equal diameters, substantially as set forth.

In a combined school desk and seat, the combination of a desk body, a pedestal supporting the same, and comprising a pair of cylindrical shells or sections connected together for adjustments in vertical and horizontal planes, means for securing the pedes tal sections at their vertical adjustment, a seat provided with a cylindrical section on its underside, and a connecting frame connected to the upper section of the desk pedestal and provided with a vertical portion adapted to fit the cylindrical section of the seat, the said vertical portion of the connecting frame and the lower section of the desk pedestal having equal diameters, substantially as set forth.
